For a science project 30 students are divided into a group of six each group needs a piece of string that is 2 1/2 feet long mr.

Anuta_ua [19.1K]

Answer:

66 inches

Step-by-step explanation:

1. Yards to Feet:

1 yard= 3 feet

(6 yards)(3)= 18

6 yards = 18 feet

2. Number of Groups:

30 students/6 students per group= 5 groups

3. Total String Needed:

(5 groups)x(2.5 feet string)= 12.5 feet total string

4. Remaining String:

18 feet-12.5 feet= 5.5 feet

5. Feet to Inches:

1 foot= 12 inches

(5.5 feet)(12)= 66 inches

66 inches of string will remain

Step-by-step explanation:

The product of segment lengths is the same for the two chords.

9(21) = x(27)

x = 189/27 . . . . . divide by 27

x = 7

Show that sin (30°) = 1/2

Natali [406]

Answer:

Geometric proof in explanation.

Step-by-step explanation:

Draw an equilateral triangle.

A equilateral triangle has it's sides all congruent and all it's angles measures 60 degrees.

We are going to draw a line segment to cut the equilateral triangles into two congruent right triangles. I will do this in the attachment with p being positive.

You can see we will get 30-60-90 triangles.

We don't need to find the adjacent measurement to the angle whose measurement is 30 degrees since sine is opposite over hypotenuse.

$\sin(30^\circ)=\frac{\frac{p}{2}}{p}=\frac{p}{2} \cdot \frac{1}{p}=\frac{1}{2}$

$\sin(30^\circ)=\frac{1}{2}$

Find the distance between the coordinates (0, 4) and (10,4) and write the result in the empty box.

barxatty [35]

The distance between the coordinates (0, 4) and (10,4) is 10

Step-by-step explanation:

We need to find the distance between the coordinates (0, 4) and (10,4)

The formula used to find distance is:

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

where

$x_1=0, y_1=4, x_2=10,y_2=4$

Putting values:

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(10-0)^2+(4-4)^2}\\Distance=\sqrt{(10)^2+(0)^2}\\Distance=\sqrt{(10)^2}\\Distance=10$

So, The distance between the coordinates (0, 4) and (10,4) is 10
